4 Claims. (Cl. lee-s1) This invention relates to a fire extinguisher, orII can be opened or closed. Thetube I is the general object of theinvention being to proopened-by its valve when the device is held in vavide means whereby the liquid from the tank vertical position with theconical end downward can be discharged between the walls of a buildwhilethe tube II is opened by its valve who;
